Get out your ISN! You will be able to understand the basic ideas of probability including outcomes, events, and sample spaces. Today’s Objectives:

Warm Up Tape this into your Warm Up Section and use the deck to answer.

WWK & TOC Choose a colored pencil and ruler—draw a horizontal line underneath… the last TOC entry ( 27-28 ) the last WWK entry ( Standard Deviation )

TOC WWK If you number your WWK… start numbering at 1 again!

Big Picture

Unit 3 We are now moving to Unit 3 which is Probability. The definition of Probability is the chance that something will happen—how likely it is that some event will happen.

Probability Recall that randomness— randomly assigning subjects to treatments in experiments, or randomness in sampling in observational studies— is a key component of statistics. Probability gives us a way to measure randomness.
